Bio-information detecting apparatus

Abstract

A bio-information detecting apparatus includes: a band member curved in a C-shape, and attached around a neck part of an examinee from a back side of the neck part; and a pair of electrodes for cardiac potential measurement disposed at positions on the band member that come into contact with right and left skin surfaces of the neck part, and in the pair of electrodes, a position of the electrode on the right is located relatively more frontward than a position of the electrode on the left. The bio-information detecting apparatus further includes a substrate to optically measure a blood oxygen saturation for pulse measurement at a position on the band member that comes into contact with the neck part of the examinee, and a pressing force of the substrate against the skin surface of the neck part is 0.96 to 1.21 [N/cm2].

What is claimed is: 
     
       1. A bio-information detecting apparatus comprising:

 first and second electrodes configured for cardiac potential measurement of the examinee, the first electrode being disposed on the band member configured to come into contact with a right skin surface of the neck part of the examinee, and the second electrode being disposed on the band member configured to come into contact with a left skin surface of the neck part of the examinee, 
 wherein the first electrode is provided at a first free end of the band member, and the second electrode is provided between a center of the band member and a second free end of the band member such that the first electrode is located relatively more frontward than the second electrode, and 
 wherein the first electrode is configured to be disposed in a more frontward region than a center of the right lateral side of the neck part of the examinee based on its location on the band member, and the second electrode is configured to be disposed at a more backward position than a center of the left lateral side of the neck part of the examinee based on its location on the band member. 
 
     
     
       2. The bio-information detecting apparatus according to  claim 1 , further comprising:
 a substrate having a light emitting part and a light receiving part each of which is configured to optically measure a blood oxygen saturation for pulse measurement of the examinee, the substrate disposed at a position on the band member configured to come into contact with the neck part of the examinee, 
 wherein a pressing force of the substrate against the skin surface of the neck part is configured to be 0.96 to 1.21 [N/cm 2 ]. 
 
     
     
       3. The bio-information detecting apparatus according to  claim 1 ,
 wherein a contact surface of each of the first and second electrodes configured to come into contact with the skin surface of the neck part of the examinee is in a flat state or in a curved state in a direction in which a center portion of the contact surface protrudes more than a peripheral edge of the contact surface toward the skin surface of the neck part of the examinee not more than 1 mm. 
 
     
     
       4. The bio-information detecting apparatus according to  claim 1 ,
 wherein a contact area of each of the first and second electrodes configured to come into contact with the skin surface of the neck part of the examinee is more than 25 mm 2 . 
 
     
     
       5. The bio-information detecting apparatus according to  claim 2 ,
 wherein the substrate is provided between the first end of the band member and the center of the band member. 
 
     
     
       6. A bio-information detecting apparatus comprising:
 a band member curved in a C-shape, the band member configured to be attached in a manner as to extend along a neck part of an examinee from a back side of the neck part toward both left and right lateral sides of the neck part to a region more frontward than the left and right lateral sides of the neck part; 
 first and second electrodes configured for cardiac potential measurement of the examinee, the first electrode being disposed on the band member configured to come into contact with a right skin surface of the neck part of the examinee, and the second electrode being disposed on the band member configured to come into contact with a left skin surface of the neck part of the examinee; and 
 a substrate disposed at a position on the band member configured to come into contact with the neck part of the examinee, the substrate having a light emitting part and a light receiving part that are configured to optically measure a blood oxygen saturation for pulse measurement of the examinee, 
 wherein the first electrode is provided at a first free end of the band member, and the second electrode is provided between a center of the band member and a second free end of the band member such that the first electrode is located relatively more frontward than the second electrode, 
 wherein the first electrode is configured to be disposed in a more frontward region than a center of the right lateral side of the neck part of the examinee based on its location on the band member, and the second electrode is configured to be disposed at a more backward position than a center of the left lateral side of the neck part of the examinee based on its location on the band member, and 
 wherein a pressing force of the substrate against the skin surface of the neck part is configured to be 0.96 to 1.21 [N/cm 2 ].
